Ubuntu – Configuring Ubuntu 12.04 so that it recognizes the recently installed icc compiler

bashcommand linecompiler

I have an Ubuntu 12.04. I installed the icc compiler (composer_xe_2013_sp1.0.080) but when I try to compile using it I get the message :

icc : command not found.

I've read somewhere that when you install a new software you have to make something so that the OS gets aware of it, like modifying the bashrc file or something, but how to do it?

The compiler could be installed in any set of directories. Just look for it by using find:

find / -name icc -executable

Then you'll get a line like so:

/some/random/directory/icc

Just modify your $PATH variable like this:

export PATH="$PATH:/some/random/directory"

N.B: You are adding the directory to your path, not the icc executable.

Permission Denied – Fix Can’t Execute .out Files

Usually, g++ gives the created file execute permissions. If you do not pass the -o option, the file will be named a.out.

Two possible reasons why your file does not have the execute bit set, with their solutions:

The umask value is set to a value like 0133, thereby preventing the execute bit from being set. Solution: set the permissions explicitly:
```
chmod 755 a.out
```
The filesystem you're working on does not support Linux permissions. This could be the case if you're putting files on a FAT32-formatted flash drive. Solution: either back up the files and format it to ext2 or mount the drive with fmask=0022 or umask=0022 (omitting fmask). See the Mount options for fat section on the manual page of mount for more details.

For bash scripts which do not have the execute bit set, you could run bash file.sh. Such a feature exists for all files with executable content (compiled files and files with a shebang line #!/path/to/interpreter set). To execute files without the execute bit set, use the special file /lib/ld-linux.so.2 (or /lib/ld-linux-x86-64.so.2 for 64-bit applications) to run such a program:

/lib/ld-linux-x86-64.so.2 a.out
